Abstract:
In this project, the aim is finding the corrosion behavior and biocompatibility of metallic biomaterials in simulated body fluids.by this study we can have a wide knowledge about the behavior and use of metallic biomaterials.in this project we use three base metals. Ti (grade 5 and grade 2), stainless steel (316L and 316) and Mg alloy(AZ91 and AZ31). the media was six physiological environment( Cigada solution, Hank solution, SBF solution, Fusayama solution, Ringer solution and Tyrod’s solution). all of these environments are related to the body fluids except Fusayama solution that is an artificial saliva and is a mouth fluid. we used polarization tests to determine the corrosion behavior and actually use SEM,EDX, XRD and AAS tests to find out the biocompatibility of the substrates in the simulated body fluids. the last but not the least, we hope to have a better information about these alloys in the field of using them as implant. it means that if we have wide information about biocompatibility and corrosion behavior of these alloys we can use better coats in an efficient way to avoid their un proper characteristics
